Story I: The Scientist's Dilemma

A scientist studying the evolution of the universe needs to calculate the age of a distant star in seconds. Using the known speed of light, they must convert the distance to the star from light-years into seconds.

Benefit:

Accurate calculation of astronomical distances and timescales.

How to Do:

Multiply the number of light-years by 9,460,800,000 seconds per light-year.

Story II: The Financial Expert's Calculation

A financial expert needs to determine the total return on an investment held for five years. The investment has a 5% annual interest rate, which must be converted into seconds to calculate the exact interest earned.

Benefit:

Precise calculation of interest and investment returns over long periods.

How to Do:

Divide the annual interest rate by 365 days per year and then multiply by the number of seconds in a day (86,400).
